3 and 5 axis mills

this is off topi ( not being about a virus and all) but I wonder after
a list of 3 and 5 axis large scall (5x10x3' or 10x10x5') gantry router
companies. I only know of three companies and the list of links seems
endless and cabinetry related on a google search. I'm looking to cut
foam and occasionally more challenging materials.

Any one have links? Experience with these companies or buying a mill
would be helpful too!!
